The toilet bowl is divided into an upper body 1 and a lower body 2. The toilet body is divided into an upper body 1 and a lower body 2. The upper body 1 and the lower body 2 are divided into two parts. It is installed inside the main bodies 1 and 2.

The upper body 1 is provided with means for decomposing solids mainly consisting of solids during defecation and fibrous components such as toilet paper thrown in from the toilet opening (hereinafter both solids are simply referred to as solids). The lower main body 2 is provided with means mainly for evaporating the liquid in defecation.

First, the upper body 1 that decomposes solids will be explained. The hollow box-shaped upper body made of synthetic resin such as FRP or polyethylene has a toilet opening 5 having a toilet lid 3 and a toilet seat 4 on the front side of the upper surface. A toilet opening 5 and a toilet guide cylinder 6 are provided.
A cylindrical compost storage part 7 is provided inside the compost storage part 7, which communicates with each other through the toilet opening 5, leaving an air circulation space at the front and back. Compost P such as peat moss that is initially used to decompose the peat moss and the compost after decomposing the excrement are supported and stored in the cylindrical compost storage section.

The cylindrical compost storage section 7 is provided with an air intake section 9 for communicating with the outside of the container and taking in outside air on the upper side by arranging a pipe with a mesh cover over the intake port 10, and a compost support section. In addition to making it possible to take in outside air into the space 11 between the top surface of the compost and the ceiling surface above 8, the air is heated by an infrared heater or other general heating device so that the air has the amount of heat necessary for liquid evaporation and solid content decomposition. Heating is performed by means 12.

In the figure, reference numeral 13 denotes a rubber roller driven by a motor (not shown) for use in solid-liquid separation of feces, especially feces, and is appropriately provided below the stool guide cylinder 6 with a small gap between the rollers 13, 13.

14 is a defecation and compost stirring device rotated by a drive unit 15, and a horizontal stirring rod 1 with a △-shaped cross section or the like is installed at the bottom.
6 is provided with a length equal to or less than the inner diameter of the cylindrical compost storage part γ, and is located at the lower end above the compost support part 8, and usually has a compost support part 8.
The rotary connecting rod 21 loosely fitted into the central shaft hole 11 and the hollow rotating shaft 18 of the stirring device 14, and controlled by the guide tube 19 as necessary and locked to the hook 20 of the rotating shaft 18, is removed from the hook 20 and allowed to fall. A residue dropping rod 22 is provided, the lower end of which is located on the side of the residue dropping rod 22, and which can rotate in conjunction with the rotation of the rotating shaft 18.

23 is a switch for turning off the stirring device.

Next, to explain the lower body 2 that performs the evaporation process of liquid, it is made of the same material as the upper body 1 and molded into a box shape, and is fitted and fixed to the lower end of the upper body 1 so that it can be sealed. A handling port 24 for operating the contents inside the lower main body is provided at the front or rear part so that it can be opened and closed with a lid 25, and inside the inner wall of the side part, the uppermost stage is inclined downward from the front part to the rear part, and the lower stage is Locking shelf 2 that slopes downward from the rear to the front
6 will be provided.

The illustrated locking shelf 26 is made of synthetic resin and is integrally connected via a reinforcing plate 27, with the side surface of the uppermost locking shelf 26 fixed to the inner surface of the side wall of the lower main body.

Such a locking shelf 26 is provided in a space 28 at the front and rear of the lower body 2.
, 28 are opened, and a residue container 29 for the residue dropped from the bottom of the compost P is installed on one side so as to hang it.

As shown in the figure, the locking shelf 26 has a through hole 30 on one side for guiding the liquid downward, and the other side and the through hole 3
A liquid evaporation plate 32 is provided with a flow inhibiting part 31 for the liquid between the two sides, and allows the liquid flowing in the direction of the through hole 30 from the other side to come into contact with the air passing above it for a long time to evaporate the liquid. is listed.

The flow inhibiting portion 31 described in the embodiment has mountain portions 34 protruding in a staggered manner so as to serve as an inhibiting portion for the liquid flowing in the direction of the through hole 30 from one side of the liquid evaporating plate 32 provided with a standing wall 33 around it. A plurality of ribs 35 lower than the peaks are provided between the peaks 34, and the amount of water at the height of the ribs 35 is stored in the water storage section 36 made up of each rib 35 and the peaks. The flowed liquid is stored in the next water storage part 36, and the flow of the liquid is obstructed, and the contact time with air is maintained for a long time, contributing to liquid evaporation.

These liquid evaporation plates 32 are placed on the locking shelf 26 in alternating directions so that the through holes 30 are at the lower level, and the liquid is transferred from the uppermost liquid evaporation plate 32 to the lower one. becomes possible.

In addition, in the lowermost liquid evaporation plate 32, in the embodiment, a notch 37 is provided in the reinforcing plate 27 under the second stage liquid evaporation plate 32, and a notch 37 is provided in the lower part from the through hole 30 of the liquid evaporation plate 32. Allow the liquid to flow down.

Reference numeral 38 denotes a tray provided in the lower main body 2, which is used to store liquid and decomposed solid residue.

It is convenient to provide the tray 38 with an auxiliary evaporation plate 39 provided with a flow inhibiting portion 31 at a position below the liquid flow.

In the upper body 1 and lower body 2 as described above, a ventilation guide portion 40 is provided from the front part of the upper body 1 to the front part of the lower body 2.
Furthermore, an exhaust guide section 41 is provided that passes or does not pass from the rear of the lower body 2 to the rear of the upper body 1, and an exhaust pipe 42 is provided to communicate with this and protrude outside the toilet bowl through an exhaust fan 43. Allows the air inside to be exhausted.

The structure of the present invention is as described above. When using the present invention, by operating the exhaust fan 43, the air outside the device is discharged from the intake port 10 into the space 11 of the upper body 1 which is under negative pressure. The air is sucked and introduced through the air intake part 9, heated by the heating means 12 in the space 11, and then passed through the ventilation guide part 40 in the front part of the upper main body 1 and the compost P on the compost support part 8 to the lower part. The air is sucked into the main body 2 and then discharged from the exhaust guide section 41 to the outside of the device through the exhaust fan 43.

Therefore, the air introduced into the upper body 1 is heated to a constant temperature inside, and is used to provide heat to the solids and liquids in the flow process, or to be used for evaporation of the liquid, and then discharged to the outside of the vessel. Therefore, there is always a negative pressure inside the toilet bowl up to the exhaust fan 43, so that the odor inside the bowl does not leak from around the toilet seat.

Thus, compost P such as peat moss is placed on the compost support part 8 at the lower end of the compost storage part 7, and the heating means 12 and the exhaust fan 4
3 is activated, the toilet lid 3 is opened and the user defecates in large and small sizes, and the feces fall onto the rollers 13, 13 driven by the motor, and the liquid falls directly onto the compost P. The unabsorbed liquid is further flowed down onto the inclined liquid evaporation plate 32.

When defecating, solid-liquid separation is performed by the driven rollers 13, 13, and the liquid first flows down into the compost P, and then the solid content flows from between the rollers 13, 13 into the compost P.
fall on top.

After using the toilet, the toilet lid 3 is closed, and the drive unit 15 associated with the switch 23 rotates the stirring device 14 to improve the mixing of the solids and the compost P and to decompose it.

At this time, since the compost storage section 7 is cylindrical, the stirring rod 16,
The stirring and mixing effect by No. 16 becomes remarkable.

On the other hand, the liquid evaporation plate 3 absorbs into or passes through the compost P.
The liquid that has flowed down onto the compost P is evaporated directly from the compost P by hot air or evaporated on the liquid evaporation plate 32.

On the liquid evaporation plate 32, the liquid that has flowed down to the front of the uppermost stage is first stored in the water storage section 36 on the liquid evaporation plate 32, and the liquid that sequentially flows down is stored in the water storage section 36. The liquid component further overflows to the next water storage section 36, during which time it comes into contact with the warm air passing above it, evaporates into the air, and is discharged outside the vessel.

At this time, if the liquid evaporation is not completed by the uppermost liquid evaporation plate 32, it flows from the lower through hole 30 on the uppermost liquid evaporation plate 32 onto the lower liquid evaporation plate 32 and similarly contacts the air and evaporates. .

When evaporation is not completed on the liquid evaporation plate 32, the liquid flows down into the tray 38 via the evaporation auxiliary plate 39, and is evaporated in the tray 38.

The solid content decomposed by the compost P remains as a processing residue on the compost support part 8, so the solid content is released from the locking part of the rotary connecting rod 21 from the hook 20 as described above, and falls into the guide pipe 19. As a result, the tip of the connecting rod falls to the side of the residue dropping rod 22, and as the rotating shaft 18 rotates, the rotating connecting rod 21 also rotates, and the residue dropping rod 22 is rotated on the compost support part 8 and supported. It falls from the passage groove 44 on the uppermost liquid evaporation plate 32.

This is done by opening the handling port of the lower main body 2 for a certain period of time and storing it in the residue container 29.

Of course, it is also possible to remove the liquid evaporation plate 32 and drop the residue directly into the tray 38.

Note that if you operate the exhaust fan 43 strongly while using the toilet, you may feel cold due to the ventilation, so you can reduce the rotation speed of the exhaust fan 43 at the same time as the toilet lid 3 is opened.
It is convenient if it is related to 3.

Since the present invention is structured and operates as described above, the solid content in the stool is separated from the liquid content, falls onto the compost P, and is mixed with the compost P, so that its decomposition is rapid, and Since the liquid is evaporated in multiple stages from inside the compost P and on the liquid evaporation plate 32 and the tray 38 below the compost P, the tray is located directly below the compost like in a conventional compost toilet, and the liquid is stored in this tray. It is not a evaporation-delayed type that evaporates liquid, and can be used by a large number of people on a daily basis.

In particular, by using the compost stirring device 14 and the residue dropping rod 22, the solid content and the compost P are mixed well, and the entire compost is made to have good ventilation.
